A process is disclosed for acquiring scanned image data relating to an external body portion and/or a product applied to the external body portion. The process includes placing a transfer member in contact with an external portion of an individual to obtain a transfer image on the transfer member. The transfer image of the transfer member is scanned with an optical image scanner to obtain scanned image data. The scanned image data may be sent from a first computer associated with the scanner to a second computer at a remote location. An image corresponding to the scanned image data may be displayed and viewed to analyze a characteristic of the external body portion and/or a characteristic of a product applied to the external body portion. The process may also involve determining a recommendation of a treatment for the external portion and providing this recommendation. Another aspect relates to evaluating the product applied to the external body portion. In addition, the process may include monitoring the status of the external body portion during treatment.

A portable device for observing a typological characteristic of the body. For example, the device can be used to observe at least one characteristic of the appearance of the skin or the hair. The device can generate at least two images of the zone under examination. The images differ from each other as to a feature other than magnification and the intensity of the light source.

Device, system and method for observing a typological characteristic of the body

A device may include a display system including at least one of a mirror and a video system including a camera and a screen configured to return to a user positioned in front of the camera, an image acquired by the camera. The device may also include: a first polarizing system configured to polarize in a first direction light emitted by a light source; a second polarizing system configured to polarize in a second direction light received by the mirror or the camera; a mechanism configured to vary an angular offset between the first and second directions; and an angular-offset identifier system configured to identify at least three different angular offsets.

A method of enabling evaluation of a typological characteristic of an external body portion of an individual comprises generating a sequence of images simulating varying degrees of at least one typological characteristic of an external body portion and enabling identification of at least one image within the sequence of images that substantially corresponds to a typological characteristic of the external body portion of the individual.

Cosmetic and/or dermatological composition comprising a dispersion of a polymer system, and use of this system as a tensioning agent

A composition, in particular a cosmetic composition, which can especially be in the form of an emulsion, a gel or a vesicle dispersion, the said composition comprising a pulverulent phase in an amount of less than or equal to 80% by weight relative to the total weight of the composition, this composition comprising at least one pigment and at least one antiperspirant. Use of such a composition in cosmetics, in particular for make-up, in order to improve the staying power of the color of the composition.

A device for measuring the brightness of a surface includes a light source to send an incident beam onto the surface and a polarizer and two analyzers one for analyzing the reflected light and the other for analyzing the diffuse reflection from the surface at a selected point of incidence; light-sensitive photodetector means are provided to receive light from the analyzers; the incident light impinges on the surface under examination at an angle of between 0.degree. and 90.degree. with the incident beam polarization being perpendicular to the plane of incidence; the analyzers are located to differentiate between parallel and perpendicular polarization to provide differences in the assessment of specular and diffuse brightness.

Device designed to assess the brightness of a surface more particularly

An appliance for manual use for massaging a cutaneous covering, comprising, on the one hand, a reservoir (1) containing the product to be applied, and integral with a gripping element (2), the reservoir comprising a movable wall (4), so as to adapt its internal volume (9) to the quantity of product contained and, on the other hand, an applicator element (3) constituted by a sole (6) cooperating with the reservoir (1) and comprising at least one ball (7) held in a housing (8), which communicates with the internal volume of the reservoir (1) through at least one opening. The appliance also comprises a direct current source (12), which is situated in the said gripping element (2) and whose poles are each connected to one electrode, the first electrode (13) being a conductive covering which covers the wall of the gripping element (2) and the second electrode (14) being constituted by a conductive film which is in permanent contact with the product situated in the reservoir (1).

Massaging appliance

The device comprises: a high frequency alternating voltage generator the output of which is connected to a sensor probe 5 which is to be applied to a substrate to be measured, an amplifier the input of which is connected to the sensor probe, and a detector arranged to furnish a D.C. voltage signal based on the output from amplifier. The generator, the amplifier and the detector are located inside a metal envelope enclosure. An electromagnetic radiation shield is disposed inside the envelope to separate the amplifier and the detector from the high frequency generator. In operation, voltage output from the detector is indicative of the electrical impedance of the substrate as sensed at the probe. In the preferred application, the substrate is skin and the measured electrical impedance is indicative of the water content of the skin.

Device for measuring the water content of a substrate, in particular the

The method for measuring the elasticity of a superficial layer (2), in particular of the skin, comprises defining a zone (7) of this layer; creating a negative pressure in this zone to cause a deformation of the zone; and measuring the negative pressure necessary to cause a deformation of predetermined amplitude. The measuring device includes a sensor (3) provided with a cavity (5) defined by a rim (6) arranged to be pressed against the layer (2) to be studied, and a pump (17) for creating a negative pressure in the cavity (5). A suction opening (20) is provided in the cavity at a predetermined distance (d) from the superficial layer, in such a manner as to be obturated by the layer when the deformation attains the predetermined amplitude. A pick-up device is provided for measuring the negative pressure that has produced the deformation of predetermined amplitude.

The invention concerns a method for examining a sample whose surface comprises reliefs, and an apparatus for carrying out the method. The apparatus comprises a sample carrier plate subjected to illumination from at least two sources having different wavelengths and whose illumination axes form an acute angle of incidence on the sample carrier plate, the illumination axes of the sources being all different, and an observation system for the sample carried by the plate. The method may be used for measuring the effectiveness of a cosmetic treatment product on a skin.
